After studying at Harrow School of Art in the 1960s, Sue worked as a freelance illustrator. She moved to West Penwith in 1975, where she augmented her income as an artist, teaching printmaking at Penzance School of Art. In 1989 she moved to St Martins on the Isles of Scilly, where she ran her own gallery. Here, she was surrounded by a completely different landscape from that of Cornwall. In 2006 she returned to live in West Penwith, working from a studio at her home and exhibiting in may galleries in the South West.
